CWE-434: Unrestricted Upload of File with Dangerous Type
Reaching this weakness in Neosense - Multipurpose WordPress Theme < 1.8 takes a caller who can reach the endpoint. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.
If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Neosense - Multipurpose WordPress Theme the fix is 1.8: builds < 1.8 are affected, anything from 1.8 onward is not.

How does WordSec protect against this?
The attempt arrives as an ordinary request to Neosense - Multipurpose WordPress Theme: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Neosense - Multipurpose WordPress Theme 1.8 closes this, and updating the theme is the step that ends it.
